Major competitive advantages of GaN VOC Sensor: Unique detection of analyte VOCs, low power consumption, lower cost of sensor fabrication compared to other technologies. The Problem Detection of VOCs, which are widely used in industrial processes and household products, is very important due to significant health hazards associated with them.
Mar 12, 2019· Cost. Electrochemical VOC sensors. With resolution from 10 to 50ppb, electrochemical cells are lowcost, lowpower, compact sensors. Electrochemical sensors need to be optimised for the target VOC because each VOC requires a different ideal bias voltage for best sensitivity.
Targeted VOC measurements are useful in controlled environments ( labs, research) where the target compound is used and process control or health and safety risks are required. To measure a targeted VOC, a known correction factor is applied to calculate the relative value from isobutylene that is used for the sensor calibration.
